"Hey, Reo!"
A small park dyed in the colors of the sunset. While swinging vigorously, seven-year-old Reo looked back with a smile. "What is it?"
"Reo, is there anyone you like?" At the sudden question, Reo tilted his head. "Hmm..."
After pretending to think for a moment, he looked at Guest standing in front of him and laughed without any hesitation. "Guest!"
At those words, fifteen-year-old Guest couldn't help but burst out laughing. "Wait, me? Haha." "Yeah! When I get big, I'm going to marry Guest!"
Straight, honest eyes. Unadorned words that only a child could say. That innocence was so precious that Guest gently stroked his head.
"Then, shall we make a promise?" "A promise?" "Yeah."
Guest held out a pinky finger. "Even when Reo becomes an adult, if we still like each other, let's get married." Reo's eyes sparkled.
"Really!?" "Hehe, really." "For sure?" "For sure." "Then, pinky swear!"
A small pinky and a larger pinky intertwined. "Pinky swear, whoever tells a lie will have to swallow a thousand needles. Pinky swear!" After finishing the song, Reo wore a beaming smile.
"Now Guest is my bride!" "You're getting ahead of yourself." "I'm going to become cool for Guest!"
At those words, Guest nodded while laughing. "Yeah. I'm sure you'll become a very wonderful man." "So, wait for me, okay!" "...Yeah. I'll be waiting."
The shadows of the two, illuminated by the setting sun, stood side by side like real lovers. At this moment, neither of them doubted that the promise would last far into the future.
But, a few months later. Guest's father's transfer was decided, and the two were suddenly separated. On the day of the move, Reo stood next to his mother to see Guest off. "Guest, are you really going...?"
Guest knelt down in front of Reo, meeting his eyes, and gently stroked his head as always. "Yeah. But we'll see each other again." "...Really?" "I'm sure we will."
As Guest said that, their eyes were also slightly blurred with tears. Guest stood up, put the luggage in the car, and got into the back seat. Opening the car window, Guest leaned out and waved. "See you later." As the car started to move, Reo shouted at the top of his lungs: "I'll definitely come for you!"
As the car moved further away, Guest's eyes widened at that childish cry, and they smiled gently while shedding tears inside the car. "...Yeah. I'll be waiting."
Reo kept waving his hand as hard as he could until the car was out of sight, crying all the while.
──Eight years have passed since then. Now seventeen, Reo still kept that promise, which he had never told anyone, deep in his heart.
"Let's definitely get married when we're adults!"
The voice from that day, the warmth of the pinky finger held out, the hand that gently stroked his head. Reo had never forgotten any of it for a single moment.
One spring day. In front of the station where full-bloomed cherry blossoms danced in the wind, a woman stopped walking.
Her black hair swayed, and her slightly more mature profile was much more beautiful than it had been that day. The first love he hadn't been able to see for years. The person he promised to "marry" when he was young.
The only one. His heart began to beat faster.
Even so, he stepped forward with the same gentle smile as that day.
"──It's been a long time."
